Sweden March 12, 1938 d-Claims. (01.- 15-156) The present invention relates tosuction nozzles and more particularly to suction nozzles which may be used for a plurality of purposes.

In accordance with this invention an improved nozzle is formed with separate parts which may be readily separated for cleaning different materials. Also the parts are secured together in a manner to facilitate assembly and disassembly of the parts and to permit movement of one part with respect to another.

What I consider to :be novel and my invention may be better understood by reference to the following specification and appended claims when considered in connection with the accompanying drawing in which:

Fig. 1 is a side elevation of my improved nozzle;

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1;

Fig. 3 is a detailed sectional view on an enlarged scale of a portion of the nozzle;

Fig. 4 is a perspective view of a tubular sleeve;

Fig. 5 is a detailed view of a modified form of sleeve; and

Fig. 6 is a side elevation of a part of the nozzle with the sleeve partly inserted on it.

Referring to the drawing, l0 indicates a nozzle body with a tubular extension I I which is adapted to be connected to a vacuum cleaner or other suction device as by means of a flexible hose i2 shown in dotted lines. Body i0 flares outwardly from the extension i l forming va channel l3 communicating with a narrow elongated opening H at the opposite end. In body ill at each side of the opening l4, grooves ii are provided adapted to receive the edges of a tubular sleeve l6. Sleeve i8 is provided with an, opening i1 extending from one end to the other adapted to accommodate the end of'lbody ill." The opening I1 may terminate short of one end of sleeve i6 forming a portion i8 of cylindrical shape as shown in Fig. 5. At the side of sleeve l6 opposite from the opening ii, a suction opening I! is provided. Sleeve I6 is preferably inserted on part III by sliding it over the end as shown in Fig. 6 with the edges adjacent the opening I! fitting in the grooves l5. However it may befound desirable'to' form sleeve i6 of an elastic material so that it may be snapped over the end of body l0. Sleeve It forms a chamber 20 at the opening I of body l0 communicating with suctionopening I9 and channel l3. Extensions 2! are provided from body ill at each end of opening '4 extending at right angles to the axis of sleeve 16.

A nozzle mouth 22 is provided with an elongated suction openlng 23 and adapted to be connected to the body I. Nozzle mouth 22 is provided with surfaces 24 conforming in shape to the sleeve lBas best indicated in Fig. 3. Projecting portions 25 extend along the sides of extensions 2| of body l0. Nozzle mouth 22 is secured to body ill by means of bolts 26 extending through openings in projecting portions 25 and in threaded engagement with extensions 2i. Relative movement between the body l0 and part 22 r is permitted on the horizontal axis of bolts 28.

In the assembly of the complete nozzle the sleeve I6 is first inserted over the end of body Hi and then the nozzle mouth 22 located in position and secured to the body III by the bolts 28. The completely assembled nozzle is designed primarily for the cleaning of rugs or other surfaces. The articulated connection between the body I0 and nozzle mouth 22 permits access beneath low pieces of furniture. If it is desired to clean draperies, curtains orthe like, the part 22 may be removed from the body Ill by removing the bolts 26. The sub-assembly of the body It and sleeve 'iGis then used as an independent nozzle for cleaning such material.

What I claim is:

1. A duplex suction nozzle including a body part flared outwardly at one end and having an elongated opening, a tubular part formed integrally with said body communicating with the.

interior of the body and adapted to receive means for connecting the nozzle to a source of suction, a sleeve of arched shape slidable over the elongated opening with edges received in grooves of said body and having a suction opening extending substantially throughout its length for cleaning upholstered furniture and the like, and a nozzle mouth detachably secured to said body whereby the nozzle is converted into a rug cleaning device.

2. A duplex suction nozzle including a body having an elongated opening at one end, extensions from said body at each end of said opening extending at right angles to the lengthwise ex-' tent of said opening, a sleeve of arched shape slidable over the opening of said body with its edges received in grooves in the body and having a suction opening extending substantially throughout its length, said extensions forming end walls for a chamber inclosed by said sleeve for cleaningupholstered furniture and the like, and a nozzle mouth part detachably secured to said body and having an elongated suction opening communicating with the suction opening of said sleeve whereby the nozzle is converted into a rug cleaning nozzle.

3. A duplex suction nozzle including a body having a tubular part adapted to be connected to a source of suction and a flared end having an elongated opening; a sleeve of arched shape slidable over the elongated opening of said body with its edges received in grooves in the body, forming a chamber communicating with the interior of the body, and having a suction opening extending substantially throughout its length forcleaning upholstered furniture and the like; extensions closing the ends of said sleeve; and a nozzle mouth part detachably secured to said body communicating with the interior of said body, and having an elongated suction opening whereby the nozzle is converted into a rug cleaning nozzle.
